WEAVER F. FESSLER, OF GROVE CITY, PENNSYLVANIA, ASSIGNOR TO NATIONALSAFETY GUARD COMPANY, OF GROVE CITY, PENNSYLVANIA I SAFETY DEVICE.

Specification of Letters Patent.

Application filed April 3, 1912.

Serial No. 688,269.

be placed about or adjacent the exposed ro- I tating or reciprocatingelements of a machine to prevent persons or clothing from comingaccidentally into contact with the same. 1

The object of my invention is to provide asafety guard for the purposementioned which may be readily and quickly removed when it is desired tohave access to the guarded portions of the machine and which may be asreadily and as quickly replaced in position. i

A further object of my invention is to provide a device for the purposementioned adapted to inclose a large top portion of the machine and inwhich a part or parts thereof may be swung out of the way to obtainaccess to portions of the machine without necessitating the removal ofthe entire device.

A further object of my invention is to provide a device characterized asabove stated which may be folded to occupy but little space when not inuse.

A further object of the present invention is to provide a device for thepurpose stated that shall be strong and durable in order to adapt thesame for use in machine shops where heavy material is used and where theguard may be subjected to more or less severe uses.

Other objects will appear hereinafter.

With these objects in view my invention consists generally in a guardconsisting of two or more hingedly connected sections, means for rigidlybut removably supporting one of said sections and means for detach ablysecuring the other section or sections.

My invention further consists in a guard of the character underconsideration comprising a plurality of detachably and hingedlyconnected sections and means for supporting one of said sections.

My invention further consists in various details of construction andarrangements of parts all as will be fully described hereinafter andparticularly pointed out in the claim.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification and in which7 Figure 1 is a perspective view of a safety guard embodying myinvention, Fig. 2 is a top plan view of the same in folded position,Fig. 3 is a detail sectional view on sub stantially the lines 0csc ofFig. 1, and Fig. 4: is a detail perspective view illustrating the meansfor detachably connecting the several sections.

The guard is formed of two or more sec tions, as before stated, and inthe drawing I have illustrated the same as formed of three sections 1, 2and 3 respectively adapted to inclose an end and a portion of theadjacent sides of a machine. Each section is formed of a plurality ofvertical members 4 and a plurality of horizontal or longitudinal members5 which are riveted together at their points of intersection, as at 6.The

members at and 5 are flat iron bars and when riveted together form astrong rigid and durable structure. An angle iron 7 is preferablyprovided at the upper edge, riveted to the upper ends of the members aand increasing the strength and rigidity of the device. If preferredsimilar angle irons 8 may be secured to the lower ends as shown at thebottom of section 3, or the lower member may be one of the flatlongitudinally disposed bars 5 as shown at the bottom of sections 1 and2.

The sections 2 and 3 are hingedly con nected to the section 1 by meansof hinges 9, and these hinges are of such construction that the sectionsmay be readily detached from each other and are so arranged that thesections 2 and 3 may be lifted from the section 1, as shown clearly inFig. 4;. Means hereinafter described are: provided for rigidlysupporting the member 1, so that the members 2 and 3 are hingedly anddetachably mounted thereon. To rigidly, but detachably support thesection 1, I provide standards 10 comprising flat iron bars adapted tobe secured to the floor adjacent the machine to be guarded, and thereengage in slots or eyes provided on the section. The eyes or slots areformed by securing short bars 11 upon the faces of the Patented Mar. 11,1913.

bars 4 opposite the bars 5, the slots being the spaces between the bars5 and 11 and adjacent bars a. Two pairs of bars 11 are. provided, thoseof each being one above the other, so that the device is secured inposition by sliding the section down over the uprights or standards 10so that said standards engage in said slots. To remove the device as awhole, the sections 2 and 3 are swung upon their hinges so as to foldagainst the outer face of the section 1, and the device is then liftedfrom the standards 10. It is obvious that when access is desired to onlya part of the machine, the adjacent section 2 or 3 as the case may be,may be swung out of the way or entirely removed without disturbing theremainder of the device.

To'secure the hinged sections 2 and 3 in closed position I provide astandard adapted to be secured in position adjacent the end of thesection when closed, and equip the section with a latch for engaging thesame. 12 indicates the standard which comprises an upright bar providedwith means 13 for securing it in position to the machine frame and flooror other stationary place. Secured to the bar 12 are angle members 14cwhich are engaged by theilatch on the swinging section. Thislatchcomprises a bar 15 mounted for vertical reciprocation on the end member4 of the section and having projecting fingers 16 to engage the members1 on the upright or standard 12. To slidably secure the bar 15 to thesection, strips of flat iron are bent to encircle the member 4 andpreferably the ends of the bar 15, and are riveted or otherwise securedto the ends of said bar; one end of each of said strips projecting toform the fingers 16.

It is obvious that the device may be readily removed either as a Wholeor in part when it desired to have access to the portions of the machineguarded thereby, and as readily replaced. Furthermore, it is strong anddurable and will withstand Without injury the usual rough usage to whichit is liable to be subjected.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

A safety guard for machinery comprising a plurality of verticallydisposed sections hingedly connected, a pair of supporting standards,means on one of said sections for detachably and slidably engaging saidstandards, other standards arranged adjacent the free ends of the outersections and latches for securing said free ends to the last mentionedstandards, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
